ELECTRIC-LAMP FIXTURE.

ideama.

To all whom it may concern Be it known that I, GARRY J. DORMANDY, a citizen of the United States, residing at rTroy, Rensselaer county, New York, have invented certain new and useful limprovements in Electric-Lamp Fixtures, of which the following is a specification.

My invention relates to fixtures adapted to stand upon and be secured to a table or the like and to carry one or more, usually two, incandescent lamps, adjustable to a great variety of dierent positions with respect to the table or machines thereon. A series of such iixtures connected by conduits beneath the table and providing means for protecting the conducting wires or cables from being cut or injured in any way, while permitting the freest movement of each lamp, is provided by my inventiom further objects of which will appear. in this specification and be pointed out in the claims.

Tn the drawings, which represent a preferred form of my device, Figure 1 is a front elevation, partly broken away, of a single standard and all connecting parts embodying my invention; Fig. 2 is a like view showing a swivel and adjacent parts detached; Fig. 3 is a vertical section through the plane 3 3, Fig. 2.

, Premising that the fixtures are largely used in factories and mills on long tables carrying double rows of machines, as sewing machines, 11 designates a part of such table, shown in section, on which is secured, 85 as by screws 12, a standard 13 comprising a flanged column 14, a rectangular box-holding portion 15, twojoppositely extending arms 16, each terminating in a vertical split socket 17 having a set screw 18. lin each socket 17 is the vertical rotary member 19 of a double swivel 20, the upper member 21 oi which is a split socket, provided with set screw'22, for the pin 23 of a horizontally swinging part 24, shown as. provided with two longitudinally disposed apertures 25,

which may have set screws 26, for supporting a tube 27, at the outer jend of which is secured an incandescent lamp 28. A double insulating plug socket 29 is secured within part 15 of standard 13, the plug members 30 of whichY are connected by conducting ca bles 31, passing through tubes 27, to the .sockets of lamps 28. A cable 32 passes through conduit 33 and'is looped or branched upward through box 34, downward extension 35,

which is screwed into\an insulating block in the foot of column 13, through the column, and to each side of the stationary portion of socket 29.

The operation of the device will be readily understood from an inspection of the drawings.

Any desired number of standards 13 may be placed along the central longitudinal line of table 11, all connected by conduit 33. The wiring is clearly shown in Fig. 1. By the rotation of part 19 insocket 17, the lamp carrying tube 27 may be extended longitudinally of the table, as shown, transversely thereof, or at any intermediate angle. Tn like manner the rotation of part 24 permits the elevation or depression of the lamp, while tube 27 is capable of `both rotary and longitudinal movement in apertures 25. Screws 18, 22 and 26 may be adjusted either 75 to provide desired frictional resistance to the movement of parts 20, 24 and 27, or to lock them in set position.

It is obvious that certain mechanical changes may be made in my device without departing from my invention, e. g., it is evident that the double-swiveling connection between the standard and the arms 27 is non-essential'to my device'in its broadest view.

An important advantage of the invention lies in the fact that all the conducting cables, as 32, are not only fully inclosed in conduitl tubes, but also that they are positioned belowfy the table or work-bench, where they cannot under any circumstances come into contact with the work. These devices are largely usedon long tables crowded with sewing machines, which are used for stitching very light and inflammable materials, as cotton or silk. In many cases, where the wires were carried above the table, serious iires, with loss of life, have been caused by a short circuit or other accident.

What T claim is:

1. An electric lamp fixture including a standard constructed and fitted to be secured to a table; tubular means extending downward from said standard and supported thereby and adapted to pass through such table; a box at the lower end of said tubular means fitted to receive the ends of horizontal conduit tubes; oppositely extending arms at the top of said standard; lampA carrying tubes having swiveled connection ward from said standardl and supported.

thereby and adapted to pass throu h such table; a box at thelower endof sai nipple adapted to receive the ends of horizontal conduit tubes; oppositely extending arms at the top of said standard; a swivel member carried by each of said arms; a lamp carry-` ingl tube fitted for longitudinal and-rotary movement with respect to said swivel member; and an insulating box at the top of said standard 'between said arms, substantially for the purposes set forth.

3. An electric lamp fixture including a standard constructed and fitted to be secured to a table; a block of insulating material secured at the foot of said standard; a nipple secured in said block so as to be supported by said standard and to pass downward through such' table; abox at the lower end of said nipple adapted to receive the ends of horizontal conduit tubes so as to support said -tubes.;and a lamp carrying tube having swiveled connection at the top of said arm.

4. An electric lamp fixture including a standard constructed and fittad tobe secured to a.table;..l,a. block `4oflinsulating material i secured within the foot of said standard; a

' nipple secured-in said block so asto b e supported by said standard and to pass downward through such table; a box at the lower end of said nipple adapted te receive the ends of horizontal conduit tubes so as to support said tubes; oppositely extendingvarms: at the top of said standard; lamp carrying tubes each having a swiveled connection with one of said arms; and an insu-l lating box. at the top of said standard,`sub st antlally for the purposes set forth.

'5. An electric lamp fixture including a standard constructed and fitted to be secured to a table; tubular means extending down-. i

ward from said standard and adapted'to pass. through such table; aV box at thelower end of said tubular means fitted to receive the ends of horizontal conduit tubes; oppositely extending arms at the top of said standard; lamp carrying tubes having swiveled connection with said arms; and an insulating box at the top of said standard providing separate plug connections ,for a cable passing through each of said tubes, substantially for the purposesset forth.
